8 Aftershocks detected

This main shock was followed by 8 smaller aftershocks. A 3.5 magnitude earthquake hit 56 mins later 6 km (4 mi) north-east of this earthquake.

Before this earthquake struck, 8 smaller foreshocks occurred. A 3.8 magnitude earthquake hit 2 days earlier nearby.

More earthquakes coming?

Earthquakes can create aftershocks. These are generally at least 1 magnitude lower than any main shock, and as time passes the chance and strength of aftershocks decreases.

The chance that a significant earthquake like this one is followed by an even larger earthquake is not so large. On average, scientists estimate a 94% chance that a major earthquake will not be followed by an even larger one. It is still adviced to be aware of this risk

Earthquakes like this happen often in the region

Earthquakes of this strength are very common in the region. This is the strongest earthquake to hit since August 24th, 2023, when a 4.8 magnitude earthquake hit 163 km (101 mi) further east-northeast. An even stronger magnitude 7.8 earthquake struck on February 6th, 2023.

In total, 252 earthquakes with a magnitude of 4.5 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 14 days.

Tsunami very unlikely

DISCLAIMER: We strongly suggest to closely monitor advice from local authorities with regards to tsunami risks. Our analysis is based on automatically collected data from external sources, and these might contain mistakes. In addition, earthquakes can cause landslides that may lead to a tsunami, or be a followed by another, potentially stonger, earthquake.

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.

Tsunami Risk Factors

Factor Under Sea? MAG-6.5 or stronger? Shallow depth?
Explanation Almost all tsunami's are caused by earthquakes with their epicenter under sea or very near the sea. However stay cautious in coastal areas as earthquakes on land may cause landslides into sea, potentially still causing a local tsunami. Under MAG 6.5: Very unlikely to cause a tsunami.
MAG 6.5 to 7.5: Destructive tsunami's do occur, but are uncommon. Likely to observe small sea level changes.
MAG 7.6+: Earthquakes with these magnitudes might produce destructive tsunami's.
Most destructive tsunami's are caused by shallow earthquakes with a depth between 0 and 100km under the surface of the earth. Deeper tsunami's are unlikely to displace to ocean floor.
This Earthquake Not this earthquake.
This earthquake appears to have struck on land far from any coast.
Not this earthquake.
This earthquake had a magnitude of 4.5. Earthquakes of this strength are unlikely to trigger a tsunami.
This earthquake occurred at a depth of of 7 km (4 mi). Earthquakes this shallow could trigger a tsunami.
